Defined in header <cstdlib>
extern "C"   int atexit( void (*func)() ); extern "C++" int atexit( void (*func)() );

Registers the function pointed to by func to be called on normal program termination (via exit() or returning from main()).

Calling the function from several threads does not induce a data race. The implementation shall support the registration of at least 32 functions.

Parameters

func

-

pointer to a function to be called on normal program termination

Return value

​0​ if the registration succeeds, nonzero value otherwise.

Exceptions

noexcept specification:  

noexcept

  (since C++11)
